`Specificationforming part of Letters Patent No. 165,238., dated July 6, i875; application filed April 17, 1875.

Toafhom 'ttm/ny concern the city of Chicago, in the county of Cook and State of Illinois, have invented new andl useful Improvements in Paper-Damping Ma.-l chines, of which the following is a full de-` scription, reference being had to the accompanying drawings, in whichi y Figure `l `is a top or plan view; Fig.` 2, a longitudinal vertical section; and Fig. 3, a detail.

` The object of my invention is to construct a machine for wettingA rolled paper for print-` ing-presses, which will unroll and reroll the paper uniformly and evenly; and its nature consists in providing the shaft upon which the rolls are mounted with adjustable slides to fit and hold the spools or cores; in making the rolluponwhich the paper is rewound adjustable; and in combining with said machine a tension-brake. A

In thegdrawings, A represents the main frame B, a secondary frame,mounted on the main frame; G, an anti-friction roller; D, the driving-roller; E, the roller upon which the paper is rerolled F, the shaft upon which the mill-rolls of paper are mounted; G, slides on the shaftgf F, for centering and holding the spools; VH, the brake; I, brake-lever; J, swinging arms, supporting the roll-shaft E K, shaft upon which, or with which, the arms` J turn L, shaft for adjusting the pitch of the arms J and the position of the roller E M, screw-shafts for advancing or receding the shaft K; N, journal-bearings for the shaft K, and through which the screw-shafts M pass; 0, frame or case forthe bearing-blocks N; P, hand-wheel for operating shaft L; Q, wheel on shaft F, upon which the tension-brake H operates; R, the sliding or wetting board; aV

b, miter or other suitable gear-Wheelsfor operating the screw-shafts M by the shaft L; c, journal-bearings for theV shafts M 5 d, similar bearings for the shaft L; c, hinge or pivot of the brake-shoe f, support for the brake-leverrod couplings; g, a T-shaped rod coupling; h, rod or link connecting the brake-,shoe with the coupling g z', rod connecting the coupling A H g with the lower end of the hand-leverI; t",` Be it known that I, UoNEADj KAHLER, of`

rod for holding the outer` end of thecoupling the varying openings of the spools or cores upon which the paper is originally wound.4

`The frames A B are made usually of iron,

but they may be made of any suitable mateable for transferring ordinary rolled paper. The shaft F is usually made square, so as to prevent the slides G from turning or revolving thereonl without clutolles or other fastening. The slides `Gr are tted to the shaft, so as to move back and forth thereon, and they are provided with inclines l, so as to t into and securely hold the cores or spools upon which the paper is rolled at the mill. The

as may be most convenient. The arms are applied or fastened to the shaft K, and their upper ends are provided with open journalbearings, so that the rollers E can be readily taken out or inserted. The journals N are f1tted into the case O, which is provided with feathers, as shown at Fig. 3, over which grooves in journal-blocks are fitted. The shafts M pass through these `blocks and are provided with screw-threads, so that by revolving them the blocks N can be moved. backward or forward. They may be moved in unison by turning the shaft L, by means of the hand-wheel I?, or by other suitable means, so as to adjust the position of the rollerV E, in reference to the roller D, as the amount of paper on the roller E increases.

Sometimes the paper is strained more on one side than on the other, so as to cause the to correct this tendency, and make the paper wind true, the shaft L is drawn back so as to shafts M 'may be turned by hand till the paper runs true. These adjustments are imand without unequal strain, it is not only liable to tear in the wetting-machine, but if g ,'j, screw-nuts for forcing theslides G into the ends of the spools; @lock-nuts, and Z inclines on the slides G, for fitting them into rial, and the machine is made of a width suitpower is applied to the roller D at either end,

paper to run to one side or wrinkle. In order disengage the wheels a b, when either of the portant, for, unless the paper is wound true may be held by the lock-nut k.

upon it, it climbs up on the roller D, and inter-` feres with the tension and the feed, as the roller D mayturn when E is nearly full without revolving it, so as to wind the paper tightly and uniformly. As the paper usually lies about twenty-four hours after being wet before it is put in the press, it is important that it should be wound true and even at the ends of the rolls, for if it is not so wound the drying will be unequal, which will cause the paper to tear in the press.

The tension-brake is applied to the outer end of the spool-shaft F by means of the Wheel Q and the shoe H, which is brought to bear upon the wheel by means of the lever I. The

lever I is pivoted above itsv connection with the rod i, so that it is a push-rod, as shown 5 but by changing the pivot it may be made to operate as a draft-rod.

The operator cannot only regulate the tension of the paper bylneans of the brake, but can stop the paper from unwinding from the spool in case of any tear or breakage.

In operation,the roll .of paper with'its vspool is placed on the shaft F and crowded onto the slide G, nearest the brake. The other slide G is then pushed in and held. in position by the screw-nut j, which, for additional security, When the spool is in position, the paper is taken across the machine over the roller D, and under the roller E, around which it is given one or two turns to start it. Motion is then given to the roller D, which draws the paper from the spool and drives the roller E, on which the paper is rewound.

By driving the machine from the roller D, the varying diameter of the rolls on the roller E and shaft F does not effect or vary the speed of the paper.

A suitable sprinkler is placed over thev sliding board R, so as to wet the paper evenly as it passes over this board in its movement from the spool on shaft F to the roller E. When the roller E is full, it is taken out and another roller is put in its place. l

As the rollers E are the same ones that are used in the printing-press, a sufeient number of these rollers E to wind the required amount of paper will be necessary.

By the use of this machine the paper can be wet and rerolled so perfectly that a great sav,- ing of time is not only effected in this operation, but also a great saving of paper and time in printing from the rolls so Wound and wet.

XV hat I claim as new, and desire to secure by Letters Patent, is-

l. The combination of the roller E, journaled on the swinging arms J, with the adjustable shaft K and the driving shaft or roller D, substantially as specified.

2. The combination of the shaft L, screwshafts M, and sliding blocks N with the shaft K, arms J, roller E, and beveled wheels a. b, substantially as set forth.

3. rlhe combination of the brake H, wheel Q, and spool-shaft F with the sliding board R, driving shaft or roller D, and swinging and adjustable roller E, arms J, and adjustingshaft K, for regulating the tension of the paper and controlling the spocl, substantially as specified.
